Animation runs slowly on a sprite despite setting CCAnimation object's setDelayperUnit to lowest value

[saudahmed]

Bug: I have created a simple coin animation that executes perfectly but the delay between the frames remains the same whether I have set the delayPerUnit. Infact the delay is quite low and the frames changed very slowly. Here is my sample code that I have tried with and without CCSpriteBatchNode the results are the same.

CCSize size = CCDirector::sharedDirector()->getWinSize();

CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("coin-sprite-sheet.plist");

CCSpriteBatchNode * batchNode = CCSpriteBatchNode::create("coin-sprite-sheet.png");

this->addChild(batchNode);

CCArray * spriteFrames = CCArray::create(CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("coin-1.png"),
CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("coin-2.png"),
CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("coin-3.png"),
CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("coin-4.png"),
NULL);

CCAnimation* animation = CCAnimation::createWithSpriteFrames(spriteFrames);
animation->setDelayPerUnit(0.6); <---- change here to any value no effect

CCSprite * sprite_ = CCSprite::createWithSpriteFrameName("coin-1.png");
sprite_->setPosition(ccp(size.width/2,size.height/2));

batchNode->addChild(sprite_, 10);

CCRepeatForever * rep = CCRepeatForever::create(CCAnimate::create(animation, true));
sprite_->runAction(rep);

I believe it's a bug in cocos2dx-WindowsPhone. And on cocos2dx-Windows ccanimate action never runs and crashes. I am using currently this http://github.com/qima/cocos2d-windowsphone and also cocos2d-Windows for api 2.1. Please have you added a fix for this issue.
